Domingo Arrillaga

[15][16] In the following month, Arrillaga was a member of the Socieded team that participated in the inaugural edition of the Pyrenees Cup, helping his side to an 8–0 victory over Stade toulousain at Ondarreta Stadium in the semifinals on 17 April, but then starting and losing the final to Barcelona (1–2) on 1 May.

[21] On 28 September 1913, Arrillaga earned his first (and only) cap for Argentina in a friendly against Uruguay, playing the full 90 minutes as a forward and helping his side to a 4–0 win.

In 1933, the 43-year-old Arrillaga was appointed as the very first coach of the newly founded CD Malacitano (currently known as Málaga CF), then in the Tercera División, a position that he held for a little over a year, when he was replaced by Juan Manzanedo.

[9] In the summer of 1933, CD Malacitano participated in a one-off tournament called Copa de Andalucía, reserved only for Andalusian First Category clubs, in which they only claimed victory once in a 3–1 win over Real Betis on 23 July.

[11][25][26] He managed Peru in the friendly tournament Copa Roque Sáenz Peña, where they achieved two draws against Argentina (1–1 in both games),[11][25] and in the 1941 South American Championship in Chile, after which he was sacked, having led the team to only one win in four matches.
